We’ve compared the Canon EF-M 22mm with the slightly wider fixed 28mm f/2.8 equivalent found on the APS-C Nikon Coolpix A. The Nikon lens is just ahead of the Canon, scoring a DxOMark score of 22 but it has similar sharpness, slightly higher distortion and similar CA. Vignetting is lower as well (as you might expect from a sensor with no AA filter and micro-lenses designed to reduce shading) but the two lenses are very close and are both excellent performers overall.

Comparing the Canon 22/2 with...

I'd like to thank the Dxomark staff for this review. I have 2 remarks however:

- I think this lens should be compared with the Zeiss 24/1.8 and the Olympus 17/1.8, since those have similar eq. focal length and aperture. The canon actually beat these lenses on most features except vignetting @f2, despite being smaller, lighter and cheaper!

- You should review the Fuji X100's 23/2 ASAP, since it's also a competitor and a very sought after lens.
